摘要：
The present invention relates to a copolymer resin composition formed by polymerizing an alkyl methacrylate-based monomer, a styrene-based monomer, a phenylmaleimide-based monomer and an alkyl acrylate-based monomer and to an optical film formed using the copolymer resin composition. The resin composition of the present invention may reduce odors which may be generated during the film extrusion and have a good thermal resistance and thermal stability.
